do you remember why there was a war in the first place?
Ah, it really depends on who you talk to what answer you get.
Everyone who rebelled had different motivations. Lucifer was prideful and he would not accept humans as beings he had to love even though the Father created them. Many angels felt the same, and others, such as myself, had their own reasons for rebelling and standing alongside him. For instance, I hated humans because I knew that He loved them more than us.
Michael, and Gabriel with him, stood to defend the Father, and when they would not listen to us, we took the only path we had left. We fought.
We fought to make them see our side, to make them understand why we felt the way we did. And then it escalated to War, and finally, to Lucifer and those who stood with him being cast out of Heaven.
